Abstract (en)
[origin: WO2021233538A1] The invention relates to a device (7, 107) for stabilizing an AC voltage grid (1), having a converter (9) having an AC voltage side for connection to the AC voltage grid and a DC voltage side having two DC voltage poles and having an energy storage arrangement (E) that is connected on the DC voltage side of the converter between the DC voltage poles. The invention is distinguished by a controlled load (8) for absorbing active power or consuming active power that is arranged in series or parallel with the energy storage arrangement. The invention furthermore relates to a method for stabilizing an AC voltage grid by way of the device according to the invention.
